Original Bosch striker — part no. 1617000669 — a hardened steel hammer striker designed for the impact mechanism of Bosch cordless rotary hammers.

This genuine Bosch replacement part is the internal “frappeur”/striker that transfers the piston’s impact to the bit; it’s made to the same fit and finish as the factory unit so it drops into the GBH impact assembly without modification.

Fits example models: GBH 18 V-EC, GBH 18 V-LI and GBH 36 V-LI (check your tool’s 10‑digit type number to confirm compatibility). This listing is for the single striker (part number 1617000669, also shown as 1 617 000 669).

If you’re repairing the hammer mechanism, this original Bosch component restores proper impact transfer and timing — a small internal part that makes a big difference to drilling and chiselling performance. Bosch power tool parts are supplied as the exact replacement called out in the tool’s exploded diagram.
